Potassium

Potassium is one of the essential nutrients required for plant growth and reproduction.

It is classified as a macronutrient, just as nitrogen and phosphorus. Potassium is essential in nearly all processes needed to sustain plant growth and reproduction.

Plants deficient in potassium are less resistant to drought, excess water and high and low temperatures. Potassium affects quality factors such as size, shape, colour and vigour of the seed or grain and improves the fibre quality of cotton. Potassium increases crop yields because it increases root growth, improves drought tolerance, builds cellulose and reduces lodging and helps retard the spread of crop diseases and nematodes.
